Our microwave shuts off immediatly after starting to cook. The numbers on the dsplay flicker then the microwave totally shuts off. We have to reset the clock and date every time thhs happens.. ??????
The first thing I would check would be the magnetron TCO (thermal cut-out). This is a little safety devise that protects the magnetron in the event of overheating. These can act up even without overheating. I believe the nuetral side of this TCO runs through the board, and therefore the flickering and shutdown. When the TCO cools, it resets. If it were the door switch, you would blow the fuse and wouldn't be able to set the time without changing the fuse. There are other cavity thermostats that could be the culprit but my quess is on the magnetron TCO. When working with microwaves always unplug the unit and discharge the capacitor. This is high voltage..Good Luck

I am having the same problem with the lights flickering and then shutdown. Sometimes it takes several resettings toget the microwave to stay on.
This is exactly what mine does.
goes on for a few seconds and then shuts off and forces you to reset the date and time.....very frustrating.
Our microwave is doing the same thing. A few seconds after starting it shuts off and you have to reset the clock/date. Now it wiill not stop this cycle and so you cannot get anything heated.
y2chaos u r awesome as for all the others who suggested the tin foil fix. We were experiencing the shut-down problem tried the tin-foil fix and so far so good. Now can anyone suggest how to fix our economy without spending 800 billion dollars of OUR money?
Thanks to all
Our JVM1653SH01 has a similar problem. About half the time, the microwave halts shortly after starting to cook. It then beeps very loudly and all of the lights on the display light up. It then reboots and the clock and calendar have to be set before cooking. The problem is getting progressively worse (more frequent).
I have a very similar problem with my GE JVM1443LK01. It will cook on high for a couple of minutes and then just shuts down. It doesn't sound as if the automatic vent fan is running, the internal fan, and when it is cooking steam gathers inside the unit. The exhaust fan operates just fine. After about 15 - 30 minutes the power comes back on and I have to reset the clock. It seems to be getting worse. What are the possible issues and is it worth it to fix the unit. The unit is (3) years old.
does work
what do you do once you find the TCO magnetron?
